I am using Ocaml 3.00 on Win2000, when I do ^c^c in the caml-buffer, the
ocaml-program halts with
an application error:

---------------------------
mytop.exe - Application Error
---------------------------
The exception unknown software exception (0xc0000029) occurred in the
application at location 0x77fb0738.
Click on OK to terminate the program
Click on CANCEL to debug the program
---------------------------
OK Cancel
---------------------------

and after that the caml-toplevel says: Process caml-toplevel exited
abnormally with code 41
